Dramm Aluminum Shut-Off Valve - 3/4in Male-Female Thread

Lightweight Aluminum Shutoff Built for Aggressive Nutrient Chemistry

Brass and standard alloy valves can degrade under the high EC, low pH nutrient solutions common in hydroponic feeding programs. The Dramm Aluminum Shut-Off Valve is built to resist exactly that: an aluminum body that holds up to aggressive nutrient chemistry without corroding, in a package that is lighter than a comparable full-brass valve. The cast brass handle adds ergonomic grip and extra robustness on top of that lightweight body.

A 3/4in male-to-female thread connection integrates directly into greenhouse hose lines and standard irrigation manifolds, and the full-flow internal path keeps system pressure and output volume unrestricted.

Key Features & Benefits

• Aluminum construction: Lightweight yet highly durable, with excellent corrosion resistance and long service life in demanding grow environments.
• Handles high EC, low pH water: Specifically built to hold up to aggressive nutrient solution chemistry without corrosion issues.
• Cast brass handle: Ergonomic and robust, providing a secure grip during repeated daily use.
• 3/4in male-female thread: Threads directly into standard greenhouse hose fittings and irrigation manifolds.
• Lightweight, full-flow design: Reduces hand fatigue during extended use while keeping the internal flow path unrestricted.

Who Should Use This

Greenhouse growers and hydroponic operators running high EC, low pH nutrient solutions who need a lightweight, corrosion-resistant shut-off valve for daily hose management are the direct fit for this valve.

About Dramm

Since its founding in Manitowoc, Wisconsin in the early 1940s, Dramm Corporation has manufactured watering hardware built to withstand demanding commercial grow environments, and the Aluminum Shut-Off Valve extends that standard to operations running aggressive nutrient chemistry.

Frequently Asked Questions

Will this valve corrode with aggressive nutrient solutions?

Dramm specifically states this aluminum valve holds up to high EC, low pH water without corrosion, making it suitable for most hydroponic nutrient formulations. That is the main reason to choose it over a brass valve for feed-line service.

How does aluminum compare to brass for shut-off valves?

Aluminum is significantly lighter than brass while offering comparable corrosion resistance in hydroponic environments. That reduces hand fatigue during extended daily use.

What thread size is this valve?

3/4in male-to-female thread, compatible with standard greenhouse hose fittings and irrigation line manifolds. No adapters are needed for typical greenhouse plumbing.

Is this suitable for outdoor use?

Yes, aluminum is well-suited for both indoor and outdoor greenhouse and irrigation environments. The cast brass handle adds further durability for outdoor handling.
